MotionEvent has the history of all the points between the last event and the current one you are processing, if you are not able to keep up with them.
That said, the driver only reports samples at a limited rate, so it would still be possible to not see points at some places if the finger is moved really fast. If you really want to determine every possible key the finger hit, you will need to compute a line between the points and determine which ones intersect the line.
